Nutritional habits in patients with peripheral arterial disease: Adherence to the mediterranean diet.

INTRODUCTION

Adherence to the Mediterranean diet (Dietmed) exerts protective effects on cardiovascular disease (CVD). In the Lower Extremity Peripheral Arterial Disease (PAD) there are fewer studies that analyze these data.

OBJECTIVE

To determine adherence to Dietmed and dietary habits in patients with PAD, according to a history of CVD (coronary and/or cerebral ischaemic pathology) and according to the ankle-brachial index (ABI ≥ or <0,5).

MATERIAL AND

METHODS

Cross-sectional analytical study carried out in a tertiary hospital. The sample was collected consecutively. Sociodemographic and clinical history, ankle-brachial index (ABI) and a 14-point Dietmed adherence dietary questionnaire were included. The analysis of categorical variables was carried out using the Pearson's Chi-Square test, the T-Student's statistic test for independent samples was used for parametric variables and the U. Mann-Whitney test for non-parametric variables.

RESULTS

Of the 97 patients, 87,6% had low adherence to Dietmed, with no differences according to the severity of PAD. However, when we analysed the data according to whether or not they had a history of CVD, we observed a high adherence to some items included in Dietmed, specifically, in the CVD group, the consumption of lean meat (95,5% vs 64%; P=.004). In addition, we observed a significant difference in the consumption in the group without a history of CVD (32% vs 9,1%; P=.033).

CONCLUSION

In our population, patients with PAD, regardless of the stage of the disease and whether they had associated coronary or cerebral ischaemic pathology, had low adherence to Dietmed. Therefore, it is important to implement nutritional education programmes in patients with PAD in all stages, as well as in those patients who have already suffered a vascular event, so that they maintain adherence to healthy dietary habits in the long term.
